Servo Axis Drive – EL.GE AZMLM2B
The AZMLM2B is an electronic servo axis drive (“Servo Axis Drive”) manufactured by EL.GE (Elettronica Generale), an Italian company specialising in electronic control systems for CNC machine tools. The module belongs to the EL.GE modular drive family for brushless or DC servo motor control in precision machining applications. The part number AZMLM2B uniquely identifies the version and current rating within the manufacturer’s product range. The drive may be available in different current or voltage variants depending on the machine configuration; no distinct official alternative part number separate from the primary code is known.
The servo axis drive is the electronic module that regulates the torque, speed, and position of the servo motor connected to the controlled axis: it receives setpoints from the CNC or interpolator and closes the current, speed, and position loops in real time. In the event of a failure, the affected CNC axis becomes uncontrollable, the machine triggers an alarm, and production halts immediately; on multi-axis machines a single faulty drive can stop the entire machining cycle, resulting in potentially significant downtime costs.
EL.GE (Elettronica Generale) is an Italian company with decades of experience in designing and manufacturing electronic systems for machine tools, including servo and spindle drives, power supplies, and CNC control boards. Its products equip various Italian manufacturers of machining centres, CNC lathes, and milling machines. A significant part of the historical product range is to be considered legacy / discontinued: available mainly as used, reconditioned, or through specialist repair services.
